OOP has ruined programming.

you know what would be funny, if OP was a sophisticated troll
OP bought a 4chan pass
OP made a script to detect when a thread reaches bumplimit, if it had, it calls the "makenew dpt program"
always with himegoto or whatever her name was

Seems legit

Here is one package used: https://www.stackage.org/package/persistent

I haven't used it though so I can't explain it to you

Last time I posted here was about a year ago.

C, Lua, Entity Component System

It all works great, but I did get busy for a few months so I may have done some code I should not have. Talking to the lua VM back and forth multiple times each frame might not be a good thing. So, I would like to know any opinions on what I can change it to.

Right now the engine has a global

entity = {}

table in lua, and a global

g_entity_t

struct array in C. The C array holds the ID numbers of active indexes in the global table, and runs functions as needed (such as think, collide, etc.), it also holds some other variables like the entities name, the x y offset, the texture index, etc..

How i've been doing this is storing the ID of the index in the lua table in the array AS WELL AS storing that index number (redundantly) in the lua table index. When the internal part calls lua, it just needs to call the index. When the lua part calls an internal function, that function goes down the list and see what internal entity holds that ID and then does it's thing.

The ladder part might be why I have a slowdown. Is there a more optimized way to pass information between C and the VM without having to rely on the ID?

It's not a purely functional language like Haskell, but it is heavily inspired by them, which is very obvious in it's type system.

In C++ (hopefully without C++ features) what's the best way to resize memory without having to change pointers or alternatively resize memory with some construct that allows me to change pointers easily (first thing that comes to mind is to store a linked list pointing to every pointer with the data but that seems onerous).

I have a python script inserting data into a mysql server located on the same computer (localhost) from many files.

The script always runs fine then suddenly loses connection to the server after a few thousand lines in the first file. The only error I get is something that says "MySQL server has gone away". This happens in all both cases:
>MySQL connection object initialized at very beginning, same one used throughout
>MySQL connection object initialized just before statement then closed just after statement.

I can still interact with the MySQL server through a different command line interface while the script is running and after it stops due to the error.

I have had long running python scripts before for massive inserting/updating MySQL databases before and this has never happened until now.

What is going on and how do I fix this?

>>56023371
Make that a ? not a .

>struct pointer abuse.
Explain?

>>56019866
C's flaws are about how you're faced with inconvenient syntax when you do abstractions. But most languages do a poor job of improving the situation or add more problems.

C is of course not perfect. But it's the best I know of. While being picky about modern languages at least. They should do better because they're in a modern age.

>>56023371
You could have a pointer/reference to pointer.
The pointer to the allocated memory can change after you do a resize and it wont matter since the second pointer points to the new memory location, and the second pointer will never reallocate/resize, only the pointer it points to will change value, so it will have the same location all the time.

>>56023651
Here's an example with static pointer to dynamic pointer:

int **p = (int**)malloc(sizeof(int*));
int *data = (int*)malloc(10 * sizeof(int));
*p = data;

// somewhere else in the code
data = (int*)realloc(data, 1000 * sizeof(int));
*p = data;

>>56023806
Yeah that's far nicer than my solution at least. Thanks.

>>56024504
Hell no. Erlang is for things that must have zero downtime. Not because of crashes, updates, adding more machines to the cluster or high traffic. As an example most telephone management systems, many databases and messaging systems are written in Erlang.

>>56024572
>Hell no
So it's pretty slow then?
Well if you don't have to go for high performance in C++ why would it be difficult to make it stable?

I get that there's been projects done in it for those reasons but in the modern day is there really any reasons left?

>>56020095
ayyyy
Does that mean we also get parametric polymorphism based on types? Shit son, Python might just start to be bearable now.

>>56024583
with sepples, to update you need to SHUT IT DOWN and load a different executable, but with erlang it just keeps going, it's made specifically for phone/messaging stuff

>>56024625
>to update you need to SHUT IT DOWN
No, depends on how you write it.
But sure, having a language environment that's specifically built to do that is nice.

>>56024583
It's not terribly slow. Java-tier, I guess.
The problem with C++ is it runs on the metal. Erlang runs in a managed VM, that can detect, if a process is taking too long, spin up more actors, if a certain task is uncer high load, properly handle crashed processes and distribute everything over a cluster. That all can be done in C++, but can you as easily guarantee it will absolutely work with zero downtime?

So if I want to start programming and have basically no experience whatsoever, where should I begin?

What's the point of this thread?
You guys will never be like Terry.

>>56025585
More people use software I've written than Terry.

Something something religion something something autism.

Can you guys give me some fairly easy to understand implementations of pointers in C? Or maybe something to help me better understand their concept and use. It's just not clicking for me from the books I'm reading.

I need the pointer version of learning differentiation and integration from position/velocity/acceleration.

Sometimes I wish the people at Stack Overflow would just straight up give me the answer to my question instead of fucking dancing around it in attempts to get me to learn shit.

>>56025668
The first 3 answers to any question I've ever seen have been "here, copy paste this into your program".

Only after they have time to slap their answer down for the rep do they go back and add all the explanation.

>>56025613
>I need the pointer version of learning differentiation and integration from position/velocity/acceleration.

You're good at physics? Think height or temperature difference vs absolute height/temperature. a pointer is absolute, but the reference point is something whacky that changes everytime you start your program. An array index, or a ptrdiff, is a a difference, then you see why you can or can't add a pointer with a pointer, etc. Or maybe points vs vectors in the plane. I know that's not an implementation, but I'm still going to offer what I have, it clicked that way for me.

>>56025613
Pointers are literally just the address in memory to something. With *, you basically go to that address and get access to whatever that pointer type is.

>>56025613
Pointers are just a kind of comonad

Say you need a service or process to be running with as close to 100% uptime as possible.

What is the method of doing this on Linux, Windows, and OSX?

I've seen some applications utilize a 'helper service' or a 'process monitor' to basically keep an eye on the main service and reinitialize if necessary.

Java is fine. PHP is a fucking disaster though.

Java is a coherent language that just happens to put arbitrary roadblocks in the way, which means you need to work around the language rather than working with the language. This is a comparatively small problem next to PHP's shit, though. Java code will generally do what you expect it to. PHP will coerce "" to null and use like 300 different naming standards in the standard library and shit like that.

Don't use PHP.

Think of a packet as a candy, When you send it somewhere at every stop it gets wrapped in another layer of foil saying who wrapped it. Then when a packet is sent back it wraps it in the same multiple layers of foil and as devices unwrap a layer and send it to its next destination.

Going by this analogy when you send a packet saying you want to view google.com it will first say the socket on your PC that wants it (the program on your PC) Then it will say the MAC of your PC (which PC on your network). Than your public IP where you are on your ISP's network, etc.

>how can a server handle two independent sessions to my network ?
In addition to the address of the sender and the address of the receiver, packets include two "port number" that are there specifically to discriminate between different networked programs running on the same host. There's one for the web server (the program not the computer), usually 80, and your browser has to specify it when it contacts the computer on which it runs. Your OS assigns your browser a port number when it does that, which the other operating system receives as part of how to respond to the computer that's contacting it. Now here's the twist: evwn though thousands of browsers may be talking to the same server on the same port, it can know who's who based on the return address and the port. I know that you know that your router only has one IP address, but it acts like a single computer when viewed from the internet, and maps port numbers differently than what they are from the inside, in order to make everything work. See, >>56028873, how it's done?

What if you have two computers on your local network, and each computer has 1 browser running.
Isn't there a potential port clash there? how does the router resolve that?
